Theodora Angelina (1180-22 June 1246) was a Byzantine princess from the House of Angelos. The granddaughter of Andronikos Doukas Angelos, she was the great-granddaughter of a Byzantine emperor through one of her grandmothers. In 1203, she married Duke Leopold VI of Austria, and she was the mother of Frederick II of Austria and Margaret of Austria, Queen of Bohemia. She died in 1246, just seven days after her son Frederick, who was killed in battle with the Kingdom of Hungary.
